I'm trying to convince my department head that we should upgrade to AutoCAD Electrical 2018 (currently stuck on 2015) but he's got a mentality of 'if it ain't broke, don't fix it.' He's mainly concerned about interoperability with other programs, specifically SolidWorks 2017. Has anyone run the two programs together? And this is a stretch, but has anyone upgraded from AutoCAD Electrical 2015 to 2018 while running SolidWorks 2017 that can provide input into any potential upgrade issues?
